vEVELYN P. SPERRY, OF OAKYPARK, ILLINOIS.

To all whom it may concern.'

Be it known that I, EVELYN P. SPERRY, a citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Casement-Windows, ofwhich the following is a specification.

This invention relates to vthat class of windows known as Casementwindows which are adapted to swing horizontally to open and closedpositions.

The principal object of the invention is to provide a simple, economicaland efficient easement Window.

A further object is to provide a casement window adapted to swing toopen and closed positions and to reversed or inverted position, so as toenable the side of the window which is normally the outer side, to bewashed and cleaned from within.

A further object is to provide a casement window with hinge mechanismpivotally secured at different points to the casing and sashrespectively, in such manner as to permit the sash to swing with thepivoted hinge members to open and closed positions, and also to swingwith relation to the pivoted hinge members to reversed position, or inside out.

A further object is to provide suitable means, accessible from theinside only, for securing the sash in fixed relation to the swinginghinge portions, and yfor overcoming any tendency to sagf-suchfsecuringmeans beingY adapted to permit the sash to be readily released from suchfixed engagement and to swing freely to and from reversed position whendesired.

Other and further objects of the invention will appear from anexamination of the drawings and the following description and claims.

The linvention consists in the features, combinations and details ofconstruction hereinafter described and claimed.

In the accompanying drawings Figure 1 is a view in elevation of aeasement window constructed in accordance with my improve* ments showingthe sash in closed position as seen from the outside; FigjZ.

CASEMENT-WINDOW.

In constructing a casement window in accordance with my improvements Iprovide a window frame or outer casing a which may be of any ordinaryand well known form adapted to permit the Casement or sash to swing toopen and closed positions. A sash or easement b of suitable dimensionsis then provided, having one or more panes of glass c mounted inand'supported thereby. Hinges d are formed of metal and of suchdimensions as to afford the required strength to support the sash in anefficient inanner in all requiredl positions'. These hinges are eachformed of a butt or fixed leaf e which is secured'tothe window-casing bymeans of screws, an elongated swinging arm or leaf f, a hinge member orleaf h, and a pintle i. Each hinge arm f is ivotally secured at one endto the butt or ed `hinge member e and thereby to the window-casing bymeans of a vertical pintle or pivot pin g such pivot pin being in linewith the adjacent vertical edge of the sash, so as to permit the sash toswing thereon to any desired open or closed position.

The outer swinging ends of the horizontal hinge arms f above describedare each pivotally secured-by means of pivot pins i and hinge membershto the sash, midway between its opposite vertical edges, so as topermit the sash to swing with relation to the pivoted hinge members ft'o reversed position or inside out. The sash is adapted to be movedoutward to open and inward from open to closed position upon the pivotsg while in fixed relation to the horizontal swinging arm portions f andh of the hinges. When the sash is thus' moved outward to open positionit may be turned upon the pivots 'i to reversed position and then swungto as nearly closed position as the casing will permit. This enables theside which is normally the outer side to be cleaned while in suchreversed position. The sash may then be swung back to normal position orparallel with the swinging arm portions of the hinges and secured infixed relation thereto.

It is very desirable that means be provided whereby the sash may besecured in fixed relation to the swinging portions of the hinges andlocked in engagement therewith in such a manner that the securing meansmay be readily accessible from the inside but cannot be reached from theoutside ofv the window. It is also desirable that such securing means beadapted to bring the sash up to normal position or plumb and prevent orcorrect any tendency to sag which may be due tothe play of the parts attheir repective points of connection. ln order to accomplish this,metallic socket members are provided- .preferably one for each hingeandmounted the socket member is to be secured. A me-` tallic stud `lchaving a notch Z in one side thereofis mounted u on the swinging armportion f of each of t e hinges in such position that the stud extendsinward and into the socket member when the sash is in normal positionwith relation to the swinging hinge portions. The socket member isprovided with a key m which is slidably mounted therein in a verticallyelongated slot n. The inner edge o of this key is inclined downward andoutward in the direction of the base of the stud or toward the hingemember on which the stud is mounted, so that as the key is moveddownward while in engagement with the notch or slot l in the stud c itwill draw the stud inward into snug rigid engagement with the walls ofthe socket member. The recess or socket portion proper of the socketmember is tapered preferably on all sides, the open end of such recessbeing of gpeater area than the inner end portion thereo sides and topvand bottom so as to fit snugly in the recess orsocket member when theparts are in engagement. By this means any sagging of the sash which maytake place is overcome when the stud and socket membersare in engagingposition, and the desired rigidity of 'connection is aforded between theswinging arm portions of the hinges and the window sash. The window maythus be swung to any desired open position or to closed position, andthe sash is held rigidly by the stud and socket members in any desirednormal open or closed position, the mechanism for rigidly securing thesash to the swinging hinge arms being inaccessible from without andeasily accessible from within.

I claim:

ln a window, the combination of a'sash, a hinge member pivotally mountedadjacent to the edge of the sash and pivotally connectedwith the sash,ametallic socket member mounted upon the sash having a recess on theside toward the adjacent pivoted hinge member, a stud upon the pivotedhinge member movable into and out of engagement with the socket, and akey mounted in the socket member movable into and out of securingengagement with the stud.
